Joint Study Group on WMO Greenhouse Gas Monitoring

About us

The joint Study Group on WMO Greenhouse Gas Monitoring will work with appropriate involvement of external stakeholders, to undertake the following tasks:

(1) To develop the concept, including identifying the future vision for WMO-coordinated GHG-related activities, its outputs and expected contributions from and benefits for Members, leveraging synergies with existing frameworks such as the Global Atmosphere Watch (GAW) and the Integrated Global Greenhouse Gas Information System (IG3IS);

(2) To submit a final proposal of the concept for its architecture with identified key gaps between Members’ operational needs and existing relevant WMO activities to the 19th World Meteorological Congress in 2023;

a. Oversee and guide the further development of the concept for the GHG monitoring system, as per EC-75/Resolution 4, taking into account the need to

• Identify the primary users of GHG information and services and establish the priority needs of these users;
• Secure continued broad support for this development in the existing greenhouse gas monitoring community through building on existing activities and coordination mechanisms;
• Act without delay, given the importance of providing input to currently ongoing First Global Stocktake by the Parties to the Paris Agreement;
• Engage, as appropriate, all elements of the WMO governance structure in this development;
• Engage and closely collaborate with the wider scientific community and other UN agencies international entities (e.g. CEOS; CGMS; GEO; IOC/GOOS) with GHG monitoring activities, in particular the land surface and ocean observation and modeling communities;
• Minimize overlap with WMO activities by clearly positioning this infrastructure with respect to GAW and IG3IS;

b. Aim to present an early version of the draft proposal for the concept of this at INFCOM-2 and SERCOM-2 in October 2022 and the Research Board in December 2022 for their feedback and preliminary endorsement;

c. Convene a WMO Greenhouse Gas Monitoring Symposium in January 2023, with the aim of seeking input to the concept from a broad group of scientific, operational and policy-setting stakeholders;

d. Provide a draft concept proposal to EC-76 in February 2023, with the aim of getting EC recommendation for approval by Congress-19 in May 2023;

e. Take every opportunity to further socialize and seek input to the development of this concept, e.g., via scientific conferences, IPCC meetings, UNFCCC Workshops, COP27, IOC meetings, WMO Climate Policy Advisors.
